Can't enter text into an element on the page, why?

Question

Python

There is a website
There is a panel

You need to enter an arbitrary page number in the field where Page # / 5788 , but it seems to be simple, yes? When we try to access an element, we get an error element not interactible , okay, I understand, we need to scroll to this element until it becomes visible, but why, for example

ActionChains(self.driver) \
      .move_to_element(elem) \
      .perform()

Returns an error like
selenium.common.exceptions.JavascriptException: Message: javascript error: Cannot read property 'left' of undefined when the element itself exists and is found?
Everything described here does not work either.

Answer 1

What XPATH is the element being searched for? There is a normal input, everything should work without problems
